The photocatalytic activity of TiO2 coated on Al-modified folded mesoporous silica thin films (Al-MSF), TiO2/Al-MSF and Ti-, Al-MSF, has been investigated by monitoring the decomposition of methylene blue (MB). The TiO2/Al-MSF and Ti-, Al-MSF were prepared on substrates by two independent procedures, i.e., ion-exchange and sol-gel. The Ti-, Al-MSF was found to exhibit higher reactivity than TiO2/Al-MSF, while both films showed higher performance than conventional powdered TiO2. A detailed analysis of the origin of the photocatalytic reactivity for these TiO2 coated Al-modified mesoporous silica thin films toward the decomposition of MB is presented here.
